Patented June 2, 1931 UNITED STATES PATENT OFFICE KONRAD KARLWEISSFLOGH, F NUREMBERG, GERMANY DEVICE FOR FILLING THE CRANK CASES OFMOTOR VEHICLES WITH LU BRICATING OIL Application filed December 16,1929, Serial No. 414,524, and in Germany December 7, 1928.

The invention relates to devices for filling the crank cases of motorvehicles with lubricating oil, similar to application Serial No. 257,903filed by applicant on January 29,

1928. My present invention differs from the former device by thearrangement of a suction pipe, branching off from the filling hose insuch a manner, that the lubricant is drawn by means of the pump from anoil tank through the suction pipe and delivered to a container, which ispreferably of standardized capacity, and then is supplied by means ofthe same pump through the filling hose into the lubricant reservoir caseof the motor vehicles.

In the accompanying drawings- Fig. 1 is a view in side elevation of thedevice, Fig. 2 is a section, taken on line A-A of Fig. 1 and Fig. 3 is adetail section of a modification of the branching part between thefilling and the suction pipes.

The pump 1 is a rotary pump, the two rotors of which may be driven by ahand crank 2. The pump carries on the top a lubricating container 3which may be suitably removed and at the bottom a T-shaped branchingpiece 4 provided with a cock 5. A flexible hose 6, serving as thefilling means and a tube piece 7 are connected with the branching piece4.. The filling hose 6, in front of which a strainer 8 (Fig. 3) isinterposed, carries on its free end a mouth piece or nozzle 9, providedwith a cook 10 and may be put in a spring clamp 11 of the container 3.The tube piece 7 is detachably connected with a tube 14 by .a screwcoupling 13, a strainer 12 (Fig. 3)

being disposed between the tubes 7 and 14.

A funnel 16 is slidably arranged on the tube 4 14 and may be fixed onthe latter by means of a screw 15. The funnel 16 is connected with asleeve 17, which may slide on the tube 14, the sleeve 17 havinglongitudinal projections 18, so that channels 18a; (Fig. 2')

4 are formed between the tube 14 and the sleeve.

The operation of the device is as follows:

The tube 14, on which the sliding funnel 16 is loosely arranged, will beintroduced into a tank 19 or a storage barrel and then 'bile; The.desired quantity of l'ubricanthaving been discharged to the crank case,which quantity may be indicatedon a scale of the container 3, the cook.10, provided on the the funnel 16 is placed in the bunghole of thetank-or'storage barreland in this position fixed on the tube 14 by theclamp screw 15. Now the cock 5 is turned in such a position, that thepump 1 is connected with the tube 14, While the flexible hose 6 is cutoff from the pump 1. On turning the crank 2 in the proper-direction, thepump 1 will charge the'lubricant from the tank 19 through the tube 14into the container 3. In this way a) the air enters the tank 19 throughthe channels 18a existing between the sleeve 17 of the funnel 16 and thetube 14. A

When the desired quantity of lubricant is delivered into the container3, the cock 5 i565 turned in' such a position, that the tube 14 isclosed and the filling 'hose 6 is in communication with the pump 1; Nowwhen the crank 2 is turned in the opposite direction, the pump lpressesthe lubricant from the container into the filling hose, from which thelubricant will be charged to the reservoir case of an engine, as forinstance to the crank case of the motor of an automomouth piece 9 of thefilling hose 6 will be closed and thus will prevent the lubricant 8still contained in the hose from escaping. The lubricant, which mayoverflow the container 3 or run down on the outside of the devicebecause of leakage of some part, will be received nnel 16 andredel'ivered 8;

to the tank 19.

Instead. ofthe manifold cock 5 (Fig. 1) a non-returnvalve may bedisposedtogether wlth an ordinary cock in the branching piece 4.. Thebranching piece 4 according to Fig. 3 has the same construction as thatin 1, only with the difference, that in the T- shaped piece 4 a ballvalve 20 isarranged, serv ng as a non-return valve, while the connectlonportion with the filling hose contains an ordinary cook 21. A

The discharge of the lubricant from the tank 19 is effected by theoperation of the. pump 1 when the cock 21 is closed. When the container3 is filled, the cock 21 will be opened and the pump 1 driven by handbut now in the opposite direction. 'After this the lubricant will bedelivered into the filling hose 6 from the container 3, the non-returnvalve 20 being closed during this process.

In both constructions the device may be removed from the tube 1 1 by thescrev; nut 13 being removed. It canthenbe carried by hand to the placeWhere the oil is to be filled into a crankcase.

WVith the invention the usual strainer in the crankcase of a. motorvehickmay be.

omitted, because the lubricant itself Will be strained twice, namely,once by the strainer 12 in the tube 14 and the second time by thestrainer 8 in thefilling hose 6;

If it is. nevertheless. desired to, maintain the strainelf at the inletopening of the crank case, it: is. necessary thatthe. mouth piece of thefilling conduction 6 should be brought, into a secure and firm conneciQll Withthe inlet, pipe ot the crank case during the filling of thelubricant, in order-that; the lubricant can. be. pressed; through this.strain er by means of thepump 1-. In this case both strainersthemselves. may be. omitted; in the device. Instead; of the container 3a pipe connection mayalso be connected; With the. pump 1 it for instancethe. device should beemployed for filling lubricant'out of 011. tank,barrel or reservoin into. another. The rotary pump can. alsobe replacedby; a. pump of'another. type.

What I claim, is: I

1; A portable liquid; Withdrawing and dispensing device including aliquid; C 11.- tainer, a reversible liquid-pump havringports therein,one of the ports. communicating with the. bottom. of the container,branched conduits connected with the. other portpf thepump, oneof saidbnanchesbeing: adaptedfor immersion in. a. body ofliquid. during thefilling of the container during. rotation of the pump in. one-directionand 'the other branch being adapted to conduct liquidto a desired pointofadeliveryi during, operation ofthe. pump; in theiopposite direction,and means for connecting the second. mentioned port. of the pumpalternately with. the. first and second mentioned. branches 2. A deviceas claimed in claim 1, characterized in that the. second. mentioned;branch is; provided with avalve adjacent its terminal;

In testimony whereof I have. signed my nameto this specification.
